For me human life begins at viability, around 26 weeks ( i think that earliest viability). Its still fairly arbitrary for me to pick this, its just a date really, as all lives a viable at different points.

Its not consistent with my other principles, namely that for once I'll compromise my belief that we should look after all human no matter their condition, because the improvements in science we can make are important ones. Most of scienctific research has just bumbled itself into making profitable improvements on what we have now, rather than making breakthroughs in key areas. It may be possible for us to eventually create the neccesary stem cells alone rather than the life with it, but we'll never hit that point if the early foundational research isn't done. So for the sake of all those hit with such crippling diseases as Parkinsons, I think sacrificing human life, because that is what it is people, theres no need to dodge this one, is worth it. Hell we've been sacrificing animals left right and centre for lesser causes, like glove trims, so I don't see how losing human life is any worse.
